SMD Non-Shielded Power Inductor (SMD wirewund inductor) | High Current Power Inductor Manufacturer | Coilmaster Electronics
Manufacturer of High current open magnetic circuit construction SMD power inductor. Non-shielded SMD power inductors are passive electronic components designed to store energy in a magnetic field when current passes through them. Unlike shielded inductors, they do not use a ferrite ring core for full magnetic enclosure, making them lighter, smaller, and more cost-effective. These inductors are ideal for applications where electromagnetic interference (EMI) is not a major concern, such as DC-DC converters, power supply circuits, and other high-current designs. Coilmaster Electronics is a high-current Power Inductors, High Current Inductors, LAN Transformers, Molded Power Chokes, Chip beads, Common Mode Choke, High Frequency Transformer, RJ45 with magnetics, Multilayer Chip Inductors, Automotive grade power inductor, Automotive grade common mode choke, Automotive grade chip beads, Automotive grade transformer manufacturer from Taiwan since 1995. Coilmaster is a professional manufacturer for inductor, common mode choke, chip beads and transformer. Our vision is “Creating high-performance inductors, reducing energy loss, and contributing to sustainable” To achieve this, our engineer team is keen to design the power inductor to have better efficiency. With more than 20 years of experience in magnetic territory, Coilmaster Electronics is specialized in the production of SMD power inductors, common mode choke, high frequency transformers.
SMD Non-Shielded Power Inductor (SMD wirewund inductor)
Unshielded SMD power inductors / Open magnetic SMD power inductors
Non-shielded SMD power inductors are passive electronic components designed to store energy in a magnetic field when current passes through them. Unlike shielded inductors, they do not use a ferrite ring core for full magnetic enclosure, making them lighter, smaller, and more cost-effective. These inductors are ideal for applications where electromagnetic interference (EMI) is not a major concern, such as DC-DC converters, power supply circuits, and other high-current designs.
With their compact design, low cost, and high reliability, non-shielded SMD power inductors are a smart choice for engineers looking to optimize both performance and budget in a variety of electronic systems.
Key Advantages
Cost-Effective
The simpler production process and reduced raw material usage make non-shielded inductors generally more affordable than shielded types, making them well-suited for cost-sensitive applications.
Smaller Dimensions
Open magnetic construction eliminates the ferrite ring core, enabling a tinier footprint. This compact size is ideal for devices with limited board space.
Sufficient EMI Performance
While shielded inductors offer better EMI control by isolating the magnetic field, many applications do not require this level of suppression. In those cases, a non-shielded inductor may provide adequate EMI performance.
High Reliability
With fewer components and a simpler design, non-shielded inductors are often less prone to failure, offering robust performance under a wide range of operating conditions.
Features
- Tiny Size & Thin Profile: Optimized for high mounting density
- Open Magnetic Construction: Easier heat dissipation and reduced material cost
- Direct Electrode-Ferrite Core Contact: Improves mechanical stability and current-carrying capability
Applications
- Smartphones, Tablets, and Portable Devices: Power line filtering to ensure stable operation
- DC-DC Converters: Suitable for lower EMI requirement environments
- General Power Supply Circuits: Ideal for high-current designs where cost-effectiveness is crucial
